Answer:

Chimpanzees.

Explanation:

DNA sequence similarity is helpful to determine the evolutionary relationship between the organisms. The evolutionary tree can easily be constructed if the percentage of the DNA sequence similarity is known.

The human shows 98.8% sequence similarity with chimpanzee. The sequence similarity between human and gorilla DNA is 98.4%. This means Chimpanzee are more closely related to humans than gorillas.

Thus, the answer is chimpanzee.
